REGULATED AUTOMATIC-CLOSING VALVE.

Application filed December 16, 1908.

T 0 all whom it may concern:

Be it known that I, JOHN LINCOLN Gisi-i, a citizen of the Unit-edStates, residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented a new and useful Regulated Automatic- ClosingValve, of which the following is a specification.

The object of my present invention is to construct a regulated automaticclosing valve in such a manner, firstly, that the fluid in thevalve-casing be retained under direct pressure, until said fluid isrequired for flushing; secondly, that the fluid in the valve-casing bedischarged in a large vol ume, under direct pressure, into a dischargepipe; thirdly, that the flushing stream after passing the outlet in thevalve-casing, perform no other work or function, but that of flushing;and fourthly, after the flushing has been completed, for the regulatedautomatic closing valve to be closed'automatically, the apparatus beready to repeat its work, as hereinafter described.

Figure 1, is a perspective of my improved apparatus. Flg. 2. 1s avert1cal section thereof, with the valve K., closed. Fig. 3, is avertical section thereof,.with the valve K., open.

In the drawings a self closing valve, of the reciprocating type isshown.

Like letters of reference, refer to like parts in the several figures.

In Fig. 1,T. T. T., is the valve-casing.

N. N. are screws, to fasten fluid-tight, the removable top T., of thevalve-casing to the body or T. T., part of the valve-casing.

I., is the inlet to the valvecasing T. T. T.

0., is a discharge pipe.

S., is a spindle passing into and through the discharge pipe C.

1-1., is a handle fastened to, and operating the spindle S.

0., is an outlet from the discharge pipe G. The usual connections withthe service pipe and discharge pipe are made at 1., and 0.,respectively.

F., is a wheel mounted upon suitable bearings, within the valve-casingT. T. T. (in, a hollow float, attached to the wheel F., by the set-nut(Z. E., a slot in the rim or periphery of wheel F. R., an antifrictionroller. 13., a projecting arm from roller It. A., a supporting armfastened to the inside of the valve-casing T. T. T., and engag-Specification of Letters Patent.

ing the arm 13., thereby assisting in the proper alinement of the valveK.

D. D. D., is a connecting arm between the roller R, and the insidesurface of the valve K.

K., is the valve seat, in the valve-casing T. T. T.

K., is the reciprocating valve, in the valve-casing T. T. T". i

Z., is the valve stem, connecting the valve K., with the angle arm S.S., by means of of a movable hearing at S. S.

a. b. 0., on the wheel F., indicate different positions, to which thefloat G., may be adjusted, in order to regulate a long or short flushingstream.

t., is a movable joint in the valve stem Z.

The arm D. D. D., has cleared the roller R, from the slot E., and at thesame time raised the arm 13., through its bearing in the arm A. Thefloat G., is in the position shown in Fig. 3. The wheel F., has beenpartly rotated upon its axis. The roller K., is in contact withperiphery of wheel F.

In my invention the wheel F is operated by the float G., and the deviceperforms its work as follows: In Fig. 2. the valve K., is in the closedposition. Fluid is allowed to pass into the valve-casing T. T. T., atthe inlet I. The valve K. (Fig. 2.) being closed, the valve-casing T. T.T., is filled and the fluid is retained under direct pressure, equal tothe pressure in the service pipe. As the valve-casing T. T. T., isfilled with fluid the float G., is held submerged. This submergedposition of the float G., is accomplished by means of the roller R,engaging the slot E., forming a lock to the wheel F., and preventing thewheel F., from being rotated upon its axis. The wheel F., being held ina fixed position, and the float G., being immovably attached to thewheel F., by the set-nut (L, the float G., is therefore held in a fixedor submerged position, as the valvecasing T. T. T. is filled with fluid..This submerged position (Gr. Fig. 2.), of the float G., remains so,until the handle II, is pulled down, thereby rotating the spindle S.,upon its axis, and bringing the angle arm S. S. (Fig. 3.), into theupright position. Asthe angle arm S. S. (Fig. 8.) changes its position,a corresponding force is made to act, upon the valve stem L, whichpushes upward against the valve K., causing the valve K., to be movedaway from the valve seat K., thus opening the valve K.

and allowing the fluid to pass forward into the discharge pipe 0., to bediscl'iarged in a large volume under direct pressure. Cooperating withthe opening of the 'alve K. Fig. 3.. the arm D. D. 1).. removes theroller R. from the slot l l.. in the wheel F. thus releasing the lock tothe wheel F. The valve K., being opened and the lock to the wheel F.,being released simultaneously, the lifting powers of the submerged float(i., are instantly brought into action, and the float G., is changedfrom position. ((lr. Fig. 2.). to position (G. Fig. 3.), and during thischange of position, the float G.. rotates the wheel F upon its axis, andcarries the slot E, away from the roller R, and brings the rim orperiphery of the wheel F, in contact with the roller 1.. thereby givinga movable contact support to the roller 11., and at the same time bymeans of the arm D. D. D., holds the valve K., in the open position, andpresents the relation of parts as shown in Fig. 3.

The parts will remain as in Fig. 3.. until the contents of thevalve-casing T. T. have been discharged, when the float G., by its ownweight, will return to position (G.), and at the same time rotate thewheel F., back to position as shown in Fig. 2., and also allow the otherparts to be returned to their respective positions as shown in Fig. 2.,and leave the apparatus ready to repeat its work.

From the above description it will be noticed, that the fluid isretained under di rect pressure, in the valve-casing T. T. T., thusaccomplishing the first object of my invention. By the opening of valveK., Fig. 3 the contents of the valve-casing T. T. T., are dischargedunder direct pressure in a large volume into the discharge pipe C, thuscovering the second object of my invention. Since the regulating andworking parts of my'device are contained within the valvecasing T. T.T., the flushing stream after passing the valve seat K., which is alsothe outlet to the valve-casing T. T. T., performs no other work orfunction, but that of flushing, thus covering the third object of myinvention. After the flushing has been completed, the regulatedautomatic closing valve, is closed automatically. and all other partsare returned to their respective starting positions, thus covering thefourth object of my invention.
